What type of microphone is best for conference calls?

VISSONIC delivers expert service with a commitment to quality.

Have you spent a considerable amount on microphone technology, only to find that the outcome fell short of expectations?

Your microphone might be high-end, yet it may not perform well in the current setting.

The effectiveness of any microphone is heavily influenced by the specific environment in which it operates. Hence, it's crucial to choose the right microphone tailored to the unique characteristics of each environment. We delve deeper into environmental considerations in our blog.

A diverse selection of high-performance microphones is available that can seamlessly integrate with various video conference room configurations.

When exploring your options, keep the following factors in mind:

• Room dimensions and layout
• Specific use cases
• Type of microphone

Determining the quantity and type of microphones required is contingent upon the room’s size and setup. In adaptable spaces, the configuration can frequently change, complicating microphone selection.

For instance, in rooms with a static layout, you might opt for hardwired microphones that are fixed to desks. Conversely, in a flexible space, ceiling or wireless microphones would be more suitable.

The image above illustrates how microphones can be positioned in various room layouts.

Understanding Use Cases

Even if all rooms serve a common function, the specific needs often differ.

To secure a high-quality output, microphone choice must align with the distinct use cases relevant to each room.

As an example, in a presentation setting where an individual addresses both in-person and virtual audiences, the speaker would likely move around. For clarity and consistency in audio, a wireless handheld or lapel microphone would be essential, along with mechanisms to mute audience microphones to eliminate background noise. Audience microphones may still be useful for interactive components such as Q&A sessions, thus choosing the right type of microphone that complements the overall setup is paramount.

On the other hand, in a compact huddle space, a straightforward all-in-one collaboration device with an integrated microphone may suffice, as participants generally remain in one location and speak in one direction throughout the meeting.

Types of Microphones

Not all microphones are created equal; they vary in design, cost, and ultimately performance. In a conference room context, numerous microphone options claim universal compatibility, but that is often misleading.

As a general guideline, the closer the microphone is to the speaker, the clearer the audio quality. However, advancements in far-field microphones enable their placement in ceilings or at the front of rooms, capturing sound quality akin to that of a close microphone. Their efficacy depends heavily on room acoustics, which you can learn more about here.

Here is a closer look at different microphone types and their suitability:

Gooseneck microphones are favored in panel discussions, lecture podiums, and boardrooms, providing superior audio as speakers remain close to the mic. However, they are usually fixed, limiting speaker movement.

Handheld microphones are ideal for formats with multiple speakers, commonly utilized in concerts or lectures, allowing presenters to roam and easily pass the mic to others.

Wearable microphones deliver a hassle-free experience. A headset can also be used to interact with remote participants, particularly vital in online education setups.

Fixed tabletop microphones maintain consistency in unchanging environments. They are often labeled as boundary microphones due to their surface placement, needing speakers in close proximity for optimal performance.

Ceiling microphones eliminate table clutter and generally offer better coverage than tabletop options. They do rely heavily on room acoustics, making proper planning essential. Ceiling microphones are advantageous in flexible rooms since their positioning remains unaffected by room configuration changes, unless specific adjustments are necessary.

Beamtracking microphones are among the most sophisticated conference mics available, focusing on the speaker's voice and adapting as they move, which creates a natural dialogue for remote participants with the right digital signal processing setup.

The simplest way to differentiate microphones is whether they are directional or omnidirectional.

Each microphone is tailored to capture sound differently. Directional microphones pick up sound from a specific source, while omnidirectional microphones capture audio from all directions.

The most prevalent directional type is the cardioid microphone, exceptionally effective when two speakers are seated close. However, they struggle with multiple participants in a larger space.

Ideally, at least one cardioid microphone should be set up for every two to three speakers.

In contrast, omnidirectional microphones excel at capturing voices from multiple individuals in a surrounding area, making them ideal for larger rooms. Having several omnidirectional microphones might be necessary to effectively gather various speakers' sounds. However, they are prone to picking up background noise, necessitating noise reduction measures for HVAC systems and other distractions.

When implemented professionally and integrated seamlessly, the right microphone technology will connect effortlessly to your preferred video conferencing platform, ensuring a superior audio-visual experience.

In virtual meetings or casual video chats with friends and family, technology sometimes fails us. If you're tired of shouting to be heard, investing in an external microphone could enhance your audio quality significantly. A good microphone can also make an excellent gift for remote workers, assisting in clear communication.

Given the rise of remote work, quality microphones have become essential, as platforms like Zoom and Slack facilitate most workplace interactions. In the current hybrid work environment, a quality microphone can be a game changer, eliminating the need for frequent requests to repeat statements or speak louder.

That said, while a robust internet connection and quality webcam are critical, do not underestimate the value of a good microphone. You don't need to break the bank; even budget-friendly USB microphones can improve audio clarity drastically.

CNET utilizes a variety of microphones for Zoom meetings and video conferences. This includes USB microphones, headsets, and earbuds with high-quality mic setups. Whether you're enhancing your workspace or searching for a thoughtful tech gift for a colleague, we’ve compiled a list based on our trial experiences.

I've experimented with numerous Bluetooth headsets equipped with boom microphones, but their sound quality often disappoints. Wired headsets are superior for Zoom applications; there’s little need to stray far from the video call. The Sennheiser SC635 is a high-end wired headset, available in both 1/8-inch and USB variants; I favor the former for unmatched audio clarity. Skip the wireless earbuds; their mics are positioned too far from the mouth to provide quality audio.

Steel Series is renowned for its gaming accessories, but did you know they also produce outstanding microphones? The Alias is a pill-shaped microphone that pairs effectively with a stand. I found it works best when mounted on a boom. The sound quality is remarkable, offering volume control through a monitoring feature when headphones are plugged in. The touch mute button, when activated, displays a noticeable red X, indicating the mic is muted. With some lighting integrated, it also appeals to gamers.

I endorse the Alias; it’s currently my go-to mic for Zoom meetings.

My experience with the Blue Yeti microphone has been overwhelmingly positive. Positioned on a non-branded arm I purchased from Amazon, this setup amplifies its utility. An ergonomic volume knob and mute button on the front facilitate instant muting during calls without navigating software settings.

The audio quality is exceptional, maintaining consistent performance without issues. One minor drawback is the Micro-USB connection as opposed to USB-C, but since it remains plugged in, it's not a frequent disturbance.

Conference calls don't always mean being stationary in front of a computer. Sometimes, you may be the one presenting, requiring mobility. A Lavalier microphone clips onto your clothing, wirelessly transmitting to a small control unit connected to your computer.

The Lark Max is equipped with two mics, featuring noise-canceling capabilities and easily connecting to your iPhone, Android, or laptop via USB-C. While the sound clarity is superb, it may require you to speak slightly louder than with a stationary mic. However, the trade-off is worth it for the increased mobility and high-quality sound. Its charging case also ensures the mics and controller are readily available.
